A pedestrian in contact with a car travelling at 30mph is eight times more likely to die than if they come into contact with a car travelling 20mph.
Every 1mph below 20mph reduces casualties & severities by 6%.
A 5 mile journey at 20mph takes 10 mins.
At 30, 15 mins.
Stopping distance at 20mph is about 3 car lengths.
At 30mph, it is 6 car lengths.
Knowing all of this, I cannot understand how ANYONE would NOT support 20mph on residential streets.
The problem is, not many know all of this.
